摘要
考虑云储存中密文数据相似性较高,导致去重难度过大的问题,提出一种基于执行机构的密文数据去重算法.构建密文动态平衡跳跃表,根据对动态平衡跳跃表的构建与描述,得到抗边信道攻击的密文数据动态叠加特点.基于密文动态平衡跳跃表构建与更新结果,提出一种抗边信道攻击的数据去重框架,云储存提供商执行数据加密、数据标签查询以及数据去重三个过程.云端储存使用标签代表数据查询操作,一旦查询计数超过阈值,执行数据加密程序对该文件进行加密,并按照云储存服务商提供的执行命令对重叠密文进行去重.实验结果证明,所提方法对密文数据去重效果表现较佳,去重后云储存空间占用情况得到了明显改善.
Abstract
Considering the high similarity of ciphertext data in cloud storage,which leads to significant difficulty in deduplication,a ciphertext data deduplication algorithm based on execution mechanism is proposed.Construct a ci-phertext dynamic balance jump table,and based on the construction and description of the dynamic balance jump ta-ble,obtain the dynamic superposition characteristics of ciphertext data that resist edge channel attacks.A data dedu-plication framework against edge channel attacks is proposed based on the construction and update results of a cipher-text dynamic balanced jump table.The cloud storage provider performs three processes:data encryption,data label query,and data deduplication.Cloud storage uses tags to represent data query operations.Once the query count ex-ceeds the threshold,the data encryption program is executed to encrypt the file,and the overlapping ciphertext is de-duplicated according to the execution command provided by the cloud storage service provider.The experimental re-sults demonstrate that the proposed method performs well in deduplication of ciphertext data,and the cloud storage space occupancy is significantly improved after deduplication.
